[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are preferred embodiments of the utility model and should not be regarded as excluding other embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] In the claims, specification and the above drawings of the utility model, unless otherwise clearly defined, if the term "fixed connection" or "fixed connection" is used, it should be understood in a broad sense, that is, any connection method without a displacement relationship and relative rotation relationship between the two, that is to say, including non-detachable fixed connection, detachable fixed connection, integrated connection and fixed connection through other devices or elements.
[0021] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".
[0022] The present invention will be further described below in conjunction with the embodiments, but is not limited to the contents of the specification.
[0023] The utility model relates to a tapered hole combined processing component, which comprises: a fixed base 2, a limiter 1 and a positioning component 3, wherein the fixed base 2, the limiter 1 and the positioning component 3 are combined into a tapered hole combined processing component, and a connecting protrusion 21 is protrudingly provided on the fixed base 2; the limiter 1 can be set as a limiter plate, or can also be set as a limiter ring, or can also be set as a limiter clamp, which can limit the end or middle area of a workpiece 4 to be processed, and the extension direction of the limiter 1 forms an angle with the extension direction of the fixed base 2, and the limiter 1 is connected to one end of the fixed base 2, and abuts against the end of a cylindrical workpiece 4 to be processed, so as to form a limiter structure for limiting the circumferential rotation of the workpiece 4 to be processed.
[0024] In the present embodiment, the limit member 1 is configured as a plate-like structure, and the angle between the limit member 1 and the fixed base 2 can be a right angle, or an acute angle, or an obtuse angle. Preferably, the angle is a right angle. At this time, the end of the fixed base 2 is fixed to the limit member 1, and the bottom surface of the limit plate is flush with the bottom surface of the fixed base 2. During the processing, the fixed base 2 needs to be placed on a horizontal plane, and correspondingly, the limit member 1 is placed vertically. At this time, the limit member 1 and the fixed base 2 jointly bear the gravity of the processing assembly and the workpiece 4 to be processed to form a downward pressure, avoiding the oblique friction resistance caused by the inclination of the limit member 1, thereby ensuring that the gravity of the workpiece 4 to be processed is mainly concentrated on the fixed base 2, avoiding the limit member 1 from being crushed during use, and improving the service life of the limit member 1.
[0025] In addition, since the connecting protrusion 21 protrudes from the bottom surface of the fixed base 2, that is, the protruding surface of the connecting protrusion 21 and the installation bottom surface form an operable space, and the positioning member 31 is connected to the connecting protrusion 21 and is arranged on the same side of the fixed base 2 as the limiting structure, the positioning assembly 3 includes a positioning member 31 and a fastening clamp 32. Since the workpiece 4 to be processed is a cylindrical structure, correspondingly, the positioning member 31 has a positioning structure that is adapted to the shape of the positioning surface of the workpiece 4 to be processed, and the workpiece 4 to be processed is fixed in relative position with the fixed base 2 through the positioning member 31; the positioning surface has a certain width along the extension direction of the workpiece 4 to be processed, which can increase the contact surface with the workpiece 4 to be processed, ensuring that the workpiece 4 to be processed is placed stably on the positioning surface of the positioning member 31.
[0026] It can be understood that, since the workpiece 4 is in the shape of a long column, the fixed base 2 is in the shape of a rectangle. Figure 1 As shown, this figure is the main view of the combined component. Figure 1The direction from left to right in the figure is the length direction of the fixed base 2, which is also the extension direction of the workpiece 4 to be processed. The connecting protrusion 21 is arranged to protrude upward, that is, it protrudes along the height direction of the fixed base 2. Further, the connecting protrusion 21 extends along the width direction of the fixed base 2, that is, it is arranged in parallel with the limiting member 1. The positioning member 31 can be an annular structure, that is, a positioning ring, or the positioning member 31 can also be a semicircular structure, that is, the workpiece 4 to be processed is placed on the positioning member 31, or the positioning member 31 can also be other structures. Preferably, the positioning member 31 is a positioning ring. At this time, the positioning surface is at the bottom of the positioning member 31, and the positioning surface is arc-shaped, and the curvature of the arc is consistent with the curvature of the cylinder of the workpiece 4 to be processed. The positioning surface is aligned with the workpiece 4 to be processed. The peripheral walls of the workpiece 4 are abutted against each other, and the bottom of the positioning surface is installed on the connecting protrusion 21. After the installation is completed, the bottom wall of the workpiece 4 to be processed abuts against the positioning surface, and the positioning surface can fit on the peripheral wall of the workpiece 4 to be processed. Furthermore, in order to ensure that the workpiece 4 to be processed is evenly placed in the arc structure, the arc structure is arranged in the middle area of the connecting protrusion 21. At this time, the middle area of the connecting protrusion 21 is an arc-shaped recessed groove. Therefore, the positioning member 31 not only has a positioning effect on the workpiece 4 to be processed, but also has a certain supporting effect on the workpiece 4 to be processed, ensuring that the workpiece 4 to be processed can be stably placed on the positioning member 31, thereby avoiding the existence of knife vibration marks on the workpiece 4 to be processed, reducing the processing difficulty of the workpiece 4 to be processed, and reducing the processing cost.
[0027] In order to improve the positioning and supporting function of the positioning member 31, the positioning member 31 can be integrally formed with the connecting protrusion 21, or the positioning member 31 can be installed on the connecting protrusion 21 through a groove structure. As long as the positioning member 31 can form a positioning and stable supporting function for the workpiece 4, the connection method between the positioning member 31 and the connecting protrusion 21 is within the protection scope of the present new use.
[0028] At the same time, the fastening clamp 32 can be an annular structure, or can be set to a clamping structure. Preferably, the fastening clamp 32 has an annular structure and is sleeved on the outer periphery of the workpiece 4 to be processed. The fastening clamp 32 is connected to the end of the positioning member 31. The fastening clamp 32 includes two oppositely arranged clamping arms, and the two clamping arms are respectively clamped on both sides of the outer peripheral wall of the workpiece 4 to be processed. The clamping force formed on the workpiece 4 to be processed forms a positioning structure that keeps the workpiece 4 to be processed in a stationary state relative to the fixed base 2.
[0029] At this time, there can be two clamping arms, and the two clamping arms have opposite clamping forces on the workpiece 4 to be processed, or there can be multiple clamping arms, and the multiple clamping arms are equally spaced around and clamp the outer wall of the workpiece 4 to be processed. The clamping arms are annular clamping arms surrounding the workpiece 4 to be processed, and the clamping arms together form a clamping space. In this way, the horizontal component of the resultant force of the clamping arms on the workpiece 4 to be processed is zero, ensuring that the center of gravity of the workpiece 4 to be processed remains stationary during the processing. The data of the clamping arms are not specifically limited. Therefore, the workpiece 4 to be processed that is clamped by the fastening clamp 32 can avoid the drill bit squeezing the workpiece 4 to cause it to rotate circumferentially during the processing of the tapered pin hole 41, ensuring that the workpiece 4 to be processed is stably placed in the clamping space and remains stationary relative to the fixed base 2.
[0030] In addition, if Figure 1 and 2 As shown, the positioning member 31 is installed above the fixed base 2, and there is a certain distance between the bottom surface of the positioning member 31 and the fixed base 2, which can prevent the drill from drilling into the fixed base 2 when the workpiece 4 is processing the tapered pin hole, which is a damage to the drill and the fixed base 2. In addition, in the process of processing the tapered hole of the workpiece 4, some debris will inevitably be generated, for example, a certain metal debris, alloy debris, etc., and the debris will fall on the fixed base 2. In addition, the debris falling on the fixed base 2 is also easy to clean, which improves the cleaning efficiency. The fixed base 2 can also prevent the debris from falling directly on the machine tool to affect the running speed of the machine tool. Excessive debris will also reduce the processing accuracy of the machine tool and cause certain wear on the workpiece 4.
[0031] On this basis, a fastening lug 321 with a threaded hole extends outward along the peripheral wall of the fastening clamp 32, and the extension direction of the fastening lug 321 is set parallel to the extension direction of the connecting protrusion 21. A connecting hole is set on the side wall of the connecting protrusion 21, and the connecting hole and the threaded hole are coaxially set. The connecting hole and the threaded hole are screwed together by a pin 322 to form a connecting structure. At this time, the fastening clamp 32 can be fixedly connected with the positioning member 31 through the fastening lug 321, further ensuring that the fastening clamp 32 and the positioning member 31 remain relatively still during the taper hole process, and the length of the pin 322 can be changed to adjust the position of the taper pin hole 41. At the same time, the fastening clamp 32 can also be used for workpieces 4 to be processed with various diameters. For example, the fastening clamp 32 can be set as a split structure, so that the split structure can meet the different diameters of the workpieces 4 to be processed, so that the tapered hole combination processing assembly can be batch processed, greatly reducing the processing cost.
[0032] like Figure 3As shown, in order to ensure that the positioning member 31 can firmly position the workpiece 4 to be processed, the positioning assembly 3 also includes an annular buffer pad 33, which is arranged in the clamping space, the buffer pad 33 is coaxially arranged with the workpiece 4 to be processed, and is arranged between the workpiece 4 to be processed and the clamp arm. Since the fastening clamp 32 has a certain width, the contact surface area between the fastening clamp 32 and the workpiece to be processed can be increased to ensure the clamping force of the fastening clamp 32 on the workpiece 4 to be processed; in addition, the width of the buffer pad 33 is greater than or equal to the width of the fastening clamp 32, and the outer peripheral wall and the inner peripheral wall of the buffer pad 33 are respectively connected to the inner side of the fastening clamp 32 and the outer peripheral wall of the workpiece 4 to be processed. After installation, at least one end of the buffer pad 33 is arranged flush with the end face of the fastening clamp 32 to form a buffer structure for the workpiece 4 to be processed. Further, the buffer pad 33 and the outer peripheral wall of the workpiece 4 to be processed are interference fit. At this time, the material of the buffer pad 33 is wear-resistant material such as rubber, polystyrene, polycarbonate, etc., which can increase the friction resistance between the buffer pad 33 and the surface of the workpiece 4 to be processed, ensuring that the workpiece 4 to be processed and the positioning member 31 remain relatively still during the processing. At the same time, the buffer pad 33 can also form a protective layer on the surface of the workpiece 4 to avoid the formation of clamping marks on the contact surface due to excessive clamping force of the fastening clamp 32 on the workpiece 4, thereby improving the qualified rate of the contact surface and reducing the processing risk.
[0033] It should be noted that a positioning through hole 323 is provided on the fastening clamp 32 along the radial direction of the workpiece 4 to be processed. The positioning through hole 323 can penetrate the fastening clamp 32. The position of the positioning through hole 323 corresponds to the position of the tapered pin hole 41 of the workpiece 4 to be processed, and the hole mouth direction of the positioning through hole 323 can be extended along the height direction of the workpiece 4 to be processed, or can also be extended along the horizontal direction of the workpiece to be processed, or can also be set in an inclined direction. As long as the hole mouth direction of the positioning through hole 323 is set along the radial direction of the workpiece 4 to be processed, in this embodiment, the hole mouth direction of the positioning through hole 323 is set parallel to the protruding direction of the connecting protrusion 21, that is, the hole mouth direction is set along the height direction, and the hole mouth faces upward. At this time, the drill can process the tapered pin hole from top to bottom, that is, the drill is vertically arranged to the outer peripheral wall of the workpiece 4 to be processed, which reduces the contact area, ensures the processing accuracy of the tapered pin hole 41, and is easy to operate.
[0034] In addition, the number of the tapered pin holes 41 of the workpiece 4 to be processed is two, and the diameters of the two tapered pin holes 41 are not equal and are arranged opposite to each other in the diameter direction. At this time, the diameter of the positioning through hole 323 can be greater than or equal to the tapered pin hole 41 with a larger diameter, so that the position of the tapered pin hole 41 can be determined quickly and accurately, thereby improving the positioning accuracy. At the same time, it can also avoid the debris generated by the fastening clamp 32 to reduce the processing accuracy requirement of the tapered pin hole 41. Moreover, during the hole opening process, the drill tool stops in time when the edge of the drill tool contacts the inner wall of the positioning through hole 323, thereby ensuring that the accuracy of the tapered pin hole 41 is within the error range, further avoiding the diameter deviation of the tapered pin hole 41 during processing, and improving the accuracy of the tapered pin hole 41 during processing.
[0035] The positioning through hole 323 includes a first positioning hole 3231 and a second positioning hole 3232. The first positioning hole 3231 and the second positioning hole 3232 are relatively arranged on the outer peripheral side of the fastening clamp 32, and the diameter of the first positioning hole 3231 is greater than or equal to the diameter of the second positioning hole 3232. In addition, in order to further improve the processing accuracy of the tapered pin hole 41, the diameter of the first positioning hole 3231 is greater than or equal to the hole diameter of the upper part of the workpiece 4 to be processed, and similarly, the diameter of the second positioning hole 3232 is greater than or equal to the hole diameter of the bottom of the workpiece 4 to be processed. Preferably, the diameter of the first positioning hole 3231 is greater than the diameter of the second positioning hole 3232. For example, the diameter of the first positioning hole 3231 is 16±0.01 mm, and the diameter of the second positioning hole 3232 is 12±0.01 mm, thereby improving the hole opening accuracy.
[0036] In order to further ensure that the workpiece 4 to be processed remains relatively stationary relative to the fixed base 2 during the processing, at this time, the limit member 1 and the positioning member 31 are only subjected to vertical downward pressure and a torque that limits the circumferential rotation of the workpiece 4 to be processed. Correspondingly, a limiting protrusion 11 is provided on the upper part of the side wall of the limit member 1, and the protrusion is arranged toward the positioning member 31. The center of gravity position of the limiting protrusion 11 and the center of gravity of the positioning member 31 are maintained on the same horizontal plane, and in some embodiments, the length of the limiting protrusion 11 is equal to the outer diameter of the positioning member 31, and the bottom of the limiting protrusion 11 is higher than or equal to the bottom of the positioning member 31. Correspondingly, a limiting notch 42 is provided at the end of the workpiece 4 to be processed, and the limiting protrusion 11 cooperates with the limiting notch 42 to form a limiting structure that limits the circumferential rotation of the workpiece 4 to be processed. At this time, the drill When the tool processes the tapered pin hole 41 at the set position, it can ensure that the workpiece 4 to be processed remains stationary relative to the fixed base 2, avoid twisting or movement of the workpiece 4 to be processed, and further avoid the diameter of the tapered pin hole 41 from exceeding the tolerance, thereby ensuring the processing accuracy of the tapered pin hole 41. For example, the processing component is assembled on the wire threading machine workbench, and the electrode is aligned with the tapered hole position to open the wire threading hole. At this time, the position of the wire threading hole is the tapered hole position, and then the workpiece to be processed is cut by the slow wire processing method. In this way, a qualified tapered pin hole 41 can be cut out at one time, and the accuracy of the first positioning hole 3231 and the second positioning hole 3232 can be ensured to reach 0.01mm, and the factory qualified rate of the workpiece 4 to be processed can be guaranteed. In this way, batch processing of tapered pin holes 41 can be achieved by combining processing components, effectively reducing processing costs.
[0037] In addition, the limiting protrusion 11 can be set at an angle relative to the horizontal plane, or the limiting protrusion 11 can also be set in the vertical direction, or the limiting protrusion 11 can also be set parallel to the horizontal plane. At this time, the limiting protrusion 11 cooperates with the limiting notch 42, and correspondingly, the left end of the workpiece 4 to be processed abuts against the side wall of the limiting member 1, which can prevent the workpiece 4 to be processed from circumferential rotation during the processing, thereby ensuring the processing accuracy of the tapered pin hole 41.
[0038] In this embodiment, in order to accommodate workpieces 4 to be processed of different lengths, the limiting member 1 can be detachably connected to the fixed base 2. For example, a positioning groove or a positioning protrusion is provided at the bottom of the limiting member 1, and a positioning protrusion or a positioning groove is provided at the corresponding position of the fixed base 2, and then fixed with matching bolts and threaded holes. The structure is simple, easy to install, and can adapt to workpieces 4 to be processed of different diameters. For example, when the diameter of the left end of the workpiece 4 to be processed is larger than the diameter of the cylinder, the workpiece 4 to be processed can be first passed through the positioning member 31, and then the left end of the workpiece 4 to be processed can be abutted against the side wall of the limiting member 1. During disassembly, the limiting member 1 can be removed from the fixed base 2, and the left end of the workpiece 4 to be processed can be pulled from right to left to make the workpiece 4 to be processed separate from the positioning member 3, so that it can be smoothly removed from the processing assembly, which reduces the difficulty of disassembly and assembly, saves labor costs, and avoids damage to the workpiece 4 to be processed during disassembly and assembly.
[0039] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the embodiments of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
